Specification of Letters Patent. Patented June 20, 1911.

Application filed January 3, 1911. Serial No. 600,624.

T all whom it may concern:

Be it known that 1, JOHN W. SrURLooK, a citizen of the United States,residing at Valdosta, in the county of Lowndes and State of Georgia,have invented certain new and useful Improvements in Weighing Scales;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in scales.

One object of the invention is to provide a weighing scale having meanswhereby the desired quantity of goods to be cut from the piece isaccurately ascertained before being cut ofi.

Another object is to provide a scale of this character which will besimple, strong and durable in construction efficient and reliable inoperation and which is provided with means for conveniently moving thegoods placed thereon to the proper position for cutting off the desiredquantity.

/Vith these and other objects in view the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully de scribed and particularly pointed out in theappended claims.

In the accompanying drawings: Figure l is a side view of my improvedscale; Fig. 2 is an end view thereof; Fig. 3 is a top plan view; Fig. tis a vertical cross sectional view on the line 4.1 of Fig. 1.

Referring more particularly to the drawings, 1 denotes the base orsupporting plate of the scale on which, near one end are securedupwardly projecting bearing standards 2 having bifurcated upper ends 3in which are formed grooves or notches 4:. Pivotally supported on thestandards 2 are substantially U-shaped platform supporting bars 5 on thelower ends of which are formed laterally projecting triangular pivotlugs 6 one edge of which engages the groove l in the bifurcated ends ofthe standards 2 whereby said supporting bars 5 have a knife edgeengagement with said standards. On the upper ends of the standards 5 areformed oppositely projecting right angular attaching arms 7. The arms 7of one member of the supporting bars 5 is bolted or otherwise secured toone end of the goods supporting platform 8 while to the arms 7 of theother members of the bars 5 is bolted or otherwise secured a shelf 9 thepurpose of which will be hereinafter described. The shelf 9 is slightlylower than the platform 8 and between the adjacent edges of the shelfand platform is formed a narrow space 10 the purpose of which will alsohereinafter appear.

The opposite end of the platform 8 from the end supported on thestandards 2 is supported by means of a link 11 the upper end of which ispivotally connected to the end of the platform and the lower end ofwhich is pivotally engaged with a lever 12 arranged near the lowerplatform 1 and pivotally connected at one end to a bracket 13 which issecured to the platform 1 as shown. The opposite end of the lever 12 isloosely engaged with a hanger 14L on the upper end of which is formed ahook 15 which is loosely engaged with a loop 16 on the upper ends ofwhich are formed hooks 17. The hooks 17 are engaged with triangularlaterally projecting lugs 18 formed on the outer end of a balance beam19 arranged above and adjacent to one side of the platform 8 as shown.The balance beam 19 is provided adjacent to its outer end with laterallyprojecting triangular bearing studs 20 which are engaged with thebifurcated upper end of a supporting standard 21 the lower end of whichis secured to the platform 1 as shown. The inner end of the balance beam19 is loosely connected by a link 22 to the platform 8 adjacent to thepivoted end of the same as shown and permits the end of beam 19 to playup and down sufficiently to indicate when the platform 8 is balanced. Onthe bar 19 are slidably mounted counterbalancing weights 23 which areadapted to be adjusted to balance the platform 8 as will be hereinaftermore fully described. On the platform 8 adjacent to one edge of the sameis secured an upwardly projecting bearing frame 24 comprising endstandards 25 and a horizontally disposed bar 26. On the bar 26 isslidablymounted a supporting plate 26 to the lower end of which isloosely connected the upper end of a beam supporting rod or hanger 27the lower end of which is loosely connected to a scale beam 28 wherebysaid beam is slidably supported on the cross bar 26 of the frame 24. Thehanger 27 is connected to the beam 28 near one end of the latter andsaid short end of the beam is provided with a bifurcated head 29 in thearms of which are formed notches 30 whereby said head is slidablyengaged with the upper cross bar 31 of a fulcrum frame, the end bars orstandards 32 of which project downwardly and are secured at their lowerends to the base 1 as shown. On the beam 28 is arranged the balancingweight or pea 33 of the beam. On the outer end of the beam is arrangedthe usual weight. support or hanger 33.

Revolubly mounted in suitable bearings 3-l secured to the under side ofthe platform 8 is a goods projecting shaft 35 said shaft being arrangedtransversely beneath the platform near the delivery end of the same asshown. Fixedly mounted on the shaft are toothed wheels 36 the upperportions of which work through slots 37 formed in the platform 8. Theupper portion of the wheels project a slight distance above the top ofthe platform 8 and are adapted to engage a piece of meat or other goodsplaced on the platform. One end of the shaft 35 projects beyond one sideof the platform and on said projecting end. of the shaft is secured acrank arm 38 by means of which the shaft is operated. The crank arm 38extends on both sides of the shaft 35 and on the end of the arm oppositeto the handle is arranged a balancing weight or ball 39. The crank arm38 is adjustably secured to the outer end of the shaft 35 by a set screwor other suitable fastening means 40.

Secured to one side of the platform at the delivery end thereof andadjacent to the space between said end and the platform is a saw guide41 with which the saw or cleaver is engaged for cutting the desiredquantity of goods from the piece on the platform.

Arranged on the base plate 1 adjacent to the end of the platform 8 towhich the link 11 is attached is arranged a stop bar 5 2 by means ofwhich the platform 8 is supported when swung down by the weight of thegoods placed thereon.

My improved scale is primarily intended for weighing quantities of meatbefore the same are cut from the piece, thus providing for accuratelycutting the exact quantity desired.

In the operation of the scale the piece of meat or other goods is placedon the plat-- form 8 with one end of the meat at the end of the platformadjoining the space 10 between the platform and shelf. hen the meat hasthus been placed on the platform the scale beam 28 is shifted back onthe bar 31 of its supporting frame until the beam is opposite to or evenwith the inner end of the meat. After thus adjusting the scale beam theweights 23 are adjusted on the beam until the platform with the meatthereon balances on the supporting standards 2. The pea or weight 33 onthe scale beam 28 is then adjusted to the number of pounds it is desiredto out off from the piece of meat. In thus adjusting the pea or weightthe platform is of course overbalaneed to the number of pounds indicatedby the pea. After adjusting the weight on the scale beam the shaft 35 ofthe shifting wheels 36 is operated in the proper direction to cause thetoothed wheels 36 to feed or project the piece of meat beyond thedelivery end of the platform 8 and over the shelf 9 untilv the platform8 is again balanced which will indicate that the number of poundsindicated by the position of the pea on the scale beam is projectingbeyond the platform whereupon said projecting end of the meat is sawedor cut off from the piece and rests on the shelf 9. By this arrangementit will be readily seen that the exact quantity of meat or other goodsdesired may be accurately cut from the piece thus preventing waste orthe accumulation of small scraps which occurs in the present manner ofcutting meat. By constructing the supporting bars 5 of the platform andshelf as herein shown and described a space is provided to receive thesaw or cleaver after the same has passed through the meat in cutting offthe piece from the end of the same.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in. the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.
